| 摘 要： | 线阵的最佳差方向图能够精确求解，经典算法利用Zolotarev 多项式的特性，采用类似Dolph-Chebyshev 综合最优和方向图的方法。然而，该算法的实现非常困难。文中利用最佳差方向图的特性，提出一种新的综合方法。新方法是数值迭代算法，我们将通过实例显示其能达到工程所需的精度。新算法具有实现简单、应用灵活的优点。

| Abstract: | The optimum difference pattern can be synthesized rigorously. The method make use of theZolotarev polynomials, and is analogous to the Dolph-Chebyshev synthesis of the optimum sum patterns.However, the implementation of the method is not trivial. This paper presents a new synthesis method by takingadvantage of the properties of the optimum difference patterns. Being a numerical iteration algorithm, the newmethod is simple to implement, and is versatile to use, and can achieve the precision required by engineering. |
